JAMES BENJAMIN ALLEN, DETROIT, MICHIGAN.

LINOTYPE-MACHINE.

T 0 all whom it may concern:

Be it known that I, James BENJAMIN ALLEN, a citizen of the United States, and resident of the city of Detroit, in the county of \Vayne and State of Michigan, have invented certain new and use'tul Improvements in Linotype-Machines, of which the following is a specification.

My invention has reference more particularly to the class of machine originally known as the typograph, wherein matrices are suspended from a guide or guides which latter converge toward a certain direction, so that at'a certain time in the oper ation of the machine the matrices are assent bled in line and are redistributed after use by motion along the guides aforesaid in their diverging directions.

My invention includes, among other fea tures, improvements in the method of operating the casting box so as to allow of the production of a large line; improved means of adjusting the melting pot; improved means of preventing casting incase of the setting of too long a line and the method of locking the compressor bar in position; improved melting pot nipple; improved methods of operating on the spacers; means of operating the swinging of the top auton'iatically; improved methods of preventing injury to the macliine in case of a tight line; improved spacer distributor; improved method of making the key-board; improved matrix escapement and improved arrange ments for the cooperation of the various parts.

The annexed drawings and the following description set forth one mechanical form of the inuentionin its various parts illustrating the parts thereof.

Referring to the drawingsi Fig. l. is aperspcctive view of the improved machine from the left hand front, with the top thrown back. Fig. 2. is a vertical section of the machine from front to rear through the casting box rack bar. Fig. 3. is a view of the machine from the front with a portion broken away. to expose the interior of the casting box operating mechanism, etc. l 'ig. is a detailed view showing the rack bar operating the automatic top. Fig. 5. shows means of throwing rack bar into and outof engagement. Fig. 6. is a detail of the matrix escapement. Fig. 7. is a perspective View of the same.

Fig. 25. shows method of operation of the spacer shaft and anti splash levers. F 26. shows a vertical section of the ma-' chine from front to rear through the lower part of the spacershaft.

The machine to which the improvements are shown as applicable is one of the class of linotype machinesknown as the typegraph in which character or matrix" bars in are suspended upon ways or way wires :0 attached to what is generally known as the top, this top being pivoted on the frame and allowing reciprocating motion for the purpose of assembling and redistributing the character bars; when the top is swung forward the wires are inclined from rear to front downward so that the matrix bars may descend by gravity, while when the top is thrown back the way wires incline from frontto rear downward so that the matrix bars may be re-distributcd by gravity; there is attached to each way wire an'escapement a: and the escapemcnts are operated by finger keys a All'the above form parts of the top. The spaces consist of a wedge plate and wing n both of circular form and consist of opposed wedge faces which by revolution of the square shaft 4) upon which they are carried are increased in thickness between the matrix bars and these likewise are assembled by sliding downward upon a square shaft or guide 0 inclined from rear to front downward allowing them to be assembled by gravity. The spacers also are retained by escapemcnts r r these cscapements tor the spaces being also operated by a linger key a the spaces are redistributed byhand or by some means actuated generally by the tilting of the top. The spaces and matrix bars are led by the shaft and way wires tov the point of assembling and are formed in Figs.

order before the mouth. of the casting box and when a sufiicient number have been assembled for the purpose of the line the handle Q is rotated and the mechanism hereinafter more fully described set in motion for the purpose of obtaining-a slug or linotype having the impression 'of the characters on the matrix bars assembled with the proper spaces for words. In order to insure'this result the matrices should be properly lined for which is provided the liner bar K and the'niatrices also are kept under compression during the expansion of the spaces by the compressor bar 8, the circular wedge'space's '0 are rotated to bring their thick portions between the matrices by means of gears g and g and the whole locked in place. The melting pot a which is pivoted ate with its nipple 0 is brought into positionbefore the casting box a and by means of a plunger X in the melting pot a molten metal is forced out through the nipple 0 "so as to fill the castingbox and an impression is taken after described and passed through the cast-.

ing .box and trimmer knives carrying the slug with it and the slug then falls into the galley 'wlocated in-the rear of said knives. The-top is then thrown back and the matrix vbars re-distributed by that motion and the spaces 4) are also returned; It is to be noted that the periods of motion of the liner bar compressor bar, expansion of the spacers and the reciprocating motion of the melting pot overlap, and so with the return motion of the melting pot, shifting and revolution ofthe casting box, which is followed by the trimming and ejection of the slug; theseperiods are arranged by the proper .form given to the various cam faces and grooves and the wedge piece 9 The two fundamental motions which take place in the operation of the melting pot are, the internal motion of the plunger .X which drives the. metal out through the nipple and the motion of the melting pot upon the pivot which carries the nipple to the casting box and returns it. This latter motion is caused by the motion of the link a pivoted at a. eLink a carries a roller 0, which is located in a cam groove A so that when thecam A rotates the links a and af cause the motion of the melting pot a? upon:

the pin a This pin 06* turns withimthe sleeve a the sleeve being adjusted by four set screws on either side of the main bracket b which' pass through a'sqnare bearing a thus allowing a means of adjusting for wear. This adjustment in the foot of the melting pot allows the nipple to be brought exactly inline with'the mouth of the casting box. in the event .of any kind of wear. The link a, is also adjustable for wear by means .of the turnbuckle a. Gas is conveyed to the burner 0 and the gas nipple. 0

by means ofthe pipe 0 and the hose 0. The plunger rod a (Figs. 1 and 20) attached.

to a plston X inside thev melting pot a and cross head a and slides 04 connected to said rod are operated by means of the cam D outlined inv Fig. 3 in dotted lines and which cam Dis integral with cams A and B, and said'cam D operates the cross head through link a having a guide roll a thereon engaging with thesaid cam D, and lever a. The cross head a is secured to the sliding brackets a by means of tapered machine screws a which are removable easily and allow of removal of plunger. (See Fig. 20.) The metal pot actuating link a has a bracket at extending upwardly therefrom (Figs. 16 and 26) and on the rocking of the .pot toward the matrices this bracket allows the spring a to draw the arm a of the bell crank (Z into the depression between the collare on the compressor bar 8 and the frame a and prevents the compressor bar being moved longitudinally during the revolution of the spacers. The operation of the compression barv is described hereinafter.

The cam B, which is integral with cam A,

operates a sliding shaft b to which is attached a fork 7) and it is surrounded'by a helical spring I). The said spring impinges upon the bracket and a collar 6 and tends to push the shaft 7) on the end of which is a roller b against the cam B and b means of the fork b' acting on the shaft 1' gives to'the casting box 0 to which it is attached, a horizontal sliding motion toward and away from the matrices. This sliding motion gives clearance for the movement of the casting box' 0 after casting in 115 carrying the slug to and from the trimmer knife n and also carries the box and slug away from the matrices. On the motion of the casting box from the matrices the bracket a impinges on the projection-a of the bell crank a and removes the lever a from interposition between the collar 6 on the compressor bar 8 and the main head a and thus allows of unlocking'the' compression maintained upon the line by the r compressor bar shaft during casting, the

compressor barfcam E giving an'upwardf sliding motion to the compressor-bar s, by

means of the connection a ufland thecommotion to the compressor bar .9 by means of "pressor bartilting cam 8 giving a rocking down far enough and allows the lever a to enter the space between the frame (4 and the collar '6' which it will not do in the case of too long a 11110. This interpositnm locks the compressor bar in position so that it'cannot be drawn up beyond the end of the line by the expansion of thematrices by the spacers.

The nipple face 0 of the melting pot. is put on by screwing in brass bushings 0 into the face of the nipple head 0 and the taee is held on by steel machine screws 0* fastened into the brass bushings 0*. This owing to the difference of expansion between the steel and the brass allows of easy removal for cleaning or adjustment.

()n the nipple face 0 and below the holes a is a groove 0 which causes a protuberance of metal upon the slug and this protuberance by remaining on the slug catches in the slot 7" of the casting box see Figs. 23 and 24 during trimming of the hack, holds the slug firm while the back is trimmed and it also is trimmed otf during the operation of trimming. Inside the passage from the inelting-pt'it a to the nipple exit 0" is a perforated stop or choke 0 ,known as a hurdle and by arrangii'ig the entrance 0 from the melting pot through the hurdle c at an angle with the general course of the entrance (6 the metal in passing through the hurdle c and emission vents 11* does not spit into thetcasting box and a more even flow to the letters is arrived at, chiefly by reason of the metal pouring out of the lower part of the holes 0' on the face of the nipple evenly with the upper part.

In order to impart to the square spacer shafts 1: o a rotary motion to rotate the spaces 1 the link lover a also operates the link which is adjustable by means of the turnbuckle (see Figs. 3 and 25) and is formed at its end into a double wedge g. This wedge in its movement operates lever to which is attached weight G and thereby operates the rack which revolves two spacer shaft gears and pivoted in the main frame a?" and secured to the shafts a n. The forward end of the lever ff is slotted at g to receive the pin 7" of the rack and allows of the motion of the rack in a straight line in the main bracket if". The lever f has a roller 6 which ei'igages with the wedge.

The arm 7:? of the antisplash lever 71 pivoted at /1'- extends down between two bosses h" and It" upon the lever 0,.

Normally the lever "is held up by the highest part of the wedge {1" and said lever engaging the screw it? on the said lever keeps the end 717 in engagement with the boss it. When the melting pot moves toward the line of matrices, said wedge moves toward the right, Figs, 2 and 25, thus permitting the weight G to move the lever g? downward and rotate the shafts v. After a certain amount of movement of this lever it comes in contact with the screw h and moves the end h off the boss h thus permitting the plunger in the melting pot to operate. If the line is too tight the wedge platesc become jammed therein so that the weight G cannot rotate the shafts v and thus lever y remains in its raised position, even though it is unsupported by the wedge so that the end iv" remains on the boss h". It the line is too loose, the lever g" continues to move downwardly on the wedge until it strikes the screw it, a further movementwill throw the end b 011 to the boss 12?. normal, the wedge plates '0 become jammed when the line is properly spaced and prevent the movement of lever g just as soon as said lever comes in contact with the screw h"- and moves the end it off of boss h.

The antisplash lever it has a handle h secured to the thirdshort arm h by means of which the bell crank lever may be rotated on its pivot It and so be engaged, or disengaged by hand with either of the bosses It or bi. Allixcd to the long arm 11, are two helical springs k and IL which are at their other ends attached to the lover a and are adjusted so to tend to keep the prongs of thefork h in such a position as to admit of proper motion of the weighted arm of the lever g. This lever is pivoted at a point 5 The liner bar cam groove K, in cam K by means of roller guide la operates the adjustable sliding link /c with fork t which operates the rocking shaft 71: and the liner bar la" with hearings k and [a in the main frame 14*". The link l; is adjustable by means of the turnbuckle le -and there is shown atm" Fig. H the matrix in position preparatory to the forward movement of the liner bar which forces the matrix in against the liner pieces m and m. In the matrix stem m* is a notch at m adapted to receive the point of the liner bar If and which assists in assuri-ng rigidity of the matrices in position during casting. At the point m in the matrix is also a rabbet adapted to closely fit against the face piece mi of the compressor bar a and which assists in the same purpose. The compressor bar is also shown in section at 'llieejector bar cam groove N in gear 0 (Fig. 23) operates by means of roller guide a and link a, bracket n; and sliding shaft 21 and a fork 111; the ejector bracket; 72* being integral with the ejector bar 1%. The operation ofthc cam groove N is to slide the ejector bar a to and fro impingingupon the slug within the casting boa 0 passing through the casting box, and forcing 'the slug through the trimmer knife n the'cast- If the line is a ing box being brought in a position allowing this. The ejector bar a is guided in its operation by the tongue at working in a groove in a bracket n. The trimmer knives n are carried by plate n" which is connected tothe ejector bracket 12. and with the ejector bracket sleeve T The ejector bracket sleeve 9 turns upon the casting box shaft T The bracket n of the ejector bar a fits loosely in the slot 71 formed by the fork n so as to have longitudinal movement therein to permit the parts '11,, M, and 1' moving on the shaft 7*. Bracket a and sleeve r are adapted to turn in the main head of the machine a and said sleeve is grooved to receive the stop screw 1*", which keeps the bracket in place and prevents it ordinarily from slipping with the casting box shaft but admits of adjustment. At the back of the bracket n is a spring 1 which tends to pull the bracket upward on its pivot on the main head at the casting box shaft. In the ordinary wonking pf the machine it is carried downward by the casting box pin f impinging on stop 0", but should the box through wear or otherwise not come into place exactly, this arrangement insures that it will still keep in alinement with the ejector bar and the trimmer knife. The casting box shaft is tapered at r and a threaded nut r is screwed in between the casting box and the bracket. The casting box is slid on the tapered shaft and retained in place by a nut which engagesthe threads 1*. The casting box a has a wing 7, which has a hole 7 therein, which is adapted to engage a stop fwhen the box is slid inwardly against the anatrices, whereby said box is locked in position.

The gear 0 on shaft Q, which is in mesh with the pinion P integral withhandle Q is the means whereby the cams mentioned so far are operated, the pinion P being turned by the handle Operated by the same cam shaft Q is the spiral meshing gear Q Figs. 1 and 26, which operates a spiral gear (not shown) on the lay shaft Q Working in the cam. groove 9 in cam 4 on said shaft Q is a small guide 9 having a roller surface which gives a reciprocating motion to the rack bar 9 which is adjustable by turnbuckle and has a rack g which operates by means of the gear 9 thennatrix carrier or top shaft 9 (see Figs. 2, 4L, 5 and 26). Fixed to this shaft by two arms 9 is the matrix carrier or top 9 (see Fig. 3) and also affixed thereto are eccentric spring ba:lance"the:top .whetherin a forward or levers q with arms 9 and g which in operation are thrown on either side of the center of the shaft 9 causing extension of the springs 9 and alternately, which thrown back position. The "spring 9 is d vided into two parts working over rollers easy/to by means of a chain 9 which allows a sufiiciently long spring to be used. The springs and are attachedto the levers by pivoted brackets and 922..

The rack bar 9 is adapted to engage in the groove in the main bracket 'and works upon an eccentric roller pin which is kept in position by a thumb screw Q20 which admits of the rack bar 9 bein g thrown in and out of engagement with the gear 9. This permits of o tiona'l automatic swinging of the top or of swinging it by hand. v

The casting box cam groove It operates an adjustable yoked rack bar 1 with turnbuckle 1' by means of the guide 1"" its rack r being of suficient length to operate two pinions 1' and r The gear 1* operates the cast ng box shaft 7 giving to it a rocking motion.

The compressor bar 8 is rotated by the following means: The pinion r operated by the rack bar 1" operates the shaft 8 and on this shaft is the cam face s and stop 8 and pivoted on the compressor bar 8 is the lever s kept impinging on the cam face 8 by the spring a after casting the cam s by means of lever '8 throws the compressor bar tongue 8 away fromthe matrix line and allows redistribution. The compressor bar cam U on shaft Q? pperates by means of a roller guide at the slotted link bar a adjustable by turnbuckle u have a slide a, in which is placed a spring 10 intended to keep the roller a in its ordi; nary place, the roller u being fitted in the slide In case however, of a tight line when the compressor bar 8 operated as hereinafter described and its tongue 5' would be forced down on the line of matrices and s0 strain the machine, the force necessary compresses the spring a and allows movement of the roller 14 in the slide without damage. This operating with the anti-splash prevents casting of the line in such-a case.

The link bar u gives a longitudinal reciprocating moveme t to the compressor during assembling of the line;

lll)

bar 5 by means of a pivoted lever u, which has a forked end 16 which engages with the sleeve a. This sleeve is held to the bar 3 by means of collars u and u", whereby the bar 8 may be given its rocking movement.

The operation of the compressor bar is as follows: Assuming the bar is in the position shown in Fig. 16, the matrices m slide down their way-wires with their bottom ends above said bar .9 and occupy the space between the part a and the arm 8. The bar 3 is then rotated to bring the slot formed by the barin and the notch in said bar in the position shown in Fig. 14' and to force. the matrices a ainst the parts m and m then the liner iar 70* is operated to lock the matrices m with their'ends in said recess,m

then the bar '8 is moved longitiidinalTy whereby the arm 8* will move the matrices close to,

each other. Each spacer shaft 41 has an extension 0 and parallel with said shafts and extensions are arranged a pair of rods 7: The endsof these rods and ends of the extensions r are supported by a projection r resting on the head a Upon the extensions (6 a double spacer carrier bracket if is mounted, while on the rods 11* is arranged a bracket formed by the parts '0 and '0, which are secured together by the rod r. Said rods 71 also carrv brackets 0 which have their free ends slotted to en 'age with sheave erated from the key n.

the shafts r and their extensions as. Brackets r are secured to the parts o and r by fingers c, said fingers being secured to the brackets o by the pins '11 and to the parts o and 22 by the pins r These brackets '11 return the spacers c which may have been distributed on the shafts'e The bar o with the parts 1: and o is operated by means of a flexible cord or chain a working on the n and attached to the matrix carrier J and henceoperated by gravity and the raising of the top. There is a double spacer escapement consisting of bracket 1)" pivoted upon the pin 0 which is pivoted on the bracket 2"". This bracket is kept usually in a raised position by'the spring r When at rest the spacers n which are above the primary spacer hooks '1) aml w are kept in position thereby; the hook '0' being fixedly attached to the pin o which is pivoted in the bracket '21" and a similar hook o for the lower shaft fixedly attached to the pin "0 being similarly pivoted in the bracket 0 with a spring o tending to keep the primary hooks in an upright position and thus prevent the spacers from sliding down the shaft.

Fixedly attached to the pin a) on the side of the bracket opposite to the hook n is an arm w containing the key shown at o and fixedly attached to the lower pin 2; is an arm '2). each having a pin c upon which is pivoted the link e insuring that the arm a shall operate similarly to n. Thus it will be seen that when the key a is depressed the arms 12 and n are also depressed and as these arms are connected to the hooks o a, said hooks are also depressed.

In the primary hooks "0 and 11 are slots e which engage a pin r fixed in the secondary hooks c which is placed at a. distance from the center of the pin '0 on which th hook 11 turns and this operation of the primary hook o thus operates also the secondary hook v in a contrary motion and similarly with the lower primary book a operates the lower secondary-hook 0". The escapement for both shafts are therefore op- At 7) is a set screw which acts as a stop for the escapcment and allows adjustment thereof. The set screw These two arms 0 and "0 o also allows of adjustn'lent of the motion of the ratchet hooks. The form ofhook allows passage upward of the spacers but. not

down without operation.

The matrix escapementv a: consists of a bracket a." in which are two. sliding forks (1) and w the fork at the point 1 being adapted it) lit over the ma trix guide sulliciently close to prevent passing ofthe matrices m, down the guide. Each sliding fork re" and w is operated by a pivoted push lever .2 either end of the lever engaging with the head of one of the forks (r and w. The helical spring a: tends to keep the longer and bent fork an always close to the guide w. Through the head of the lever a passes an adjustable link or wire .11" which is operated by a pivoted letter key a This letter key M pivoted at .r consists of a letter let into the proper face and pressure by the linger upon the proper face gives by means of the other arm m of the lever a pushing motion to the pivoted lever :11 which raises the fork of w sulliciently to allow of one matrix to escape and at the same time lowers the fork of re so as to prevent more than one matrix escaping. Removal of the finger allows return of the lever :12 to its original position by the fork a For cheapness of construction the bearing of the pin :r ot'-the letter key w can be stamped out of a continuous piece of sheet meta as shown in Figs. 8, t) and 10, the two lugs :11 and 00' being cut and turned upward for the pin to pass through them; the pin holes and the slot w" are out after the lugs w and a) are turned and formed so as to retain the strength of the metal while turning 03 and :v upward. Lover 00 is adjustable tothe link 00 by means of two nuts and 01 \V hen the slug is pushed through the knives it falls into a slide 10, which carries it to the galley \V.
